The principal object ot the present invention is to provide a windowwhich is capable oit being easily reversed in position to `t`acilitatecleaning and which may be tightly and securely closed.

Another object ot our invention is to p rovide a window which is capableof being swung inwardly about a vertical axis and moved transversely toreverse its position.

.A further object of the invention is to provide a window of thecharacter indicated oit' simple, strong and durable construction.

The several features of the invention whereby the above mentioned andother obmay be attained, will be readily understood from the `tollowingdescription and accompanying drawings, in which:

lfhe window illustrated in the drawings is provided vith a window caseQ. and bottom and top parts l and (i which are mounted to slidevertically past each other within the un dow case, the two parts beingprovided f i the usual weights connected thereto by c ins or cords oneof which being indicated at i (Fig. As the two sliding parts of thewindow preferably are oi the saine construction. onlyT the bottom partwill he specilically described herein.

Each window part or section comprises an outer sash S mounted to slidein the window case, and an inner sash 10 mounted in the outer sash, bothsashes being preferably made of sheet metal which is bent into tubularform as shown and the inner sash carrying a pane of glass 11.

The inner sash is adapted to be swung inwardly about a vertical axisadjacent its left hand edge and then its axis moved transversely of theouter sash. To provide for this, pivot blocks 12 are mounted in theupper and lower ends ot' the lett hand vertical member of the inner sashand receive vertical pivot pins 141 arranged in axial alinement. Theupper pivot pin 14 is received in an aperture in the block 12, and thelower pivot pin 14C is received in a socket in the lower block 12, theupper end of the lower pivot pin engaging the bottom wall of saidsocketso as to bear the weight of the adjacent vertical edge o thewindow sash. Oil holes 13 are provided in the upper end ot the bearingblock 12 and in the adjacent outer wall of the inner sash so that thebearing may be kept well lubricated, the oil hole in the sash beingclosed by the outer sash when the inner sash is closed.

The outer ends of these pivot pins 14 are secured to supports orcarriers 15. The lower carrier 15 is mounted on rollers 16 in a guidingchannel member 18 ot sheet metal having its upper edges secured to theupper Wall ot' the lower horizontal member of the outer sash and havingits front side wall secured to an inwardly pressed portion 2O on theinner or front wall of said member of the sash. The rollers ride on thebottom horizontal wall ot the channel member 18 and the carrier isguided by the vertical side walls of said channel member. The lowerpivot pin 14 extends through a longitudinal clearance slot 22 in theupper wall of the lower horizontal member of the outer sash.

The. upper carrier 15 is mounted to slide in a downwardly openingchannel 24 formed in the bottom wall of the upper horizontal member ofthe outer sash, said carrier being guided between the vertical sidewalls of said channel.

In order to ensure smoothness of opera.- tion, a slightly bowed leafspring is held at its ends in a recess in one side of each of thecarriers 15 the center of the spring engaging one of the walls of theassociated guiding channel.

A cord 26 (Fig. 5) has one end connected to one end of the lower carrier15 and its other end secured to the opposite end of the upper carrier15, said cord passing over pulleys 28 mounted in the hollow outer sash.A cord 30 has one end secured to the end of the lower carrier l5opposite to the end to which the cord 26 is secured and its other endsecured to the opposite end of the upper carrier 15, said cord 30passing over pulleys 32 mounted within the outer sash.

The rear side of the outer sash is provided with an inwardly projectingflange 34 having its front wall provided with a transversely curvedportion 35, the portion 36 of said front wall between said curvedportion and the inner edge of said iiange being iiat. The outer rearwall of the inner sash is provided with a conversely curved portion 37and a flat portion 38 which when the inner sash is closed fits theportions and 36 of said flange of the outer sash. The portion 37 of theleft hand vertical member of the inner sash and the adjacent curvedportion 35 are curved substantially concentrically of the axis ofthepivot pins 14 but the centers of said curved portions 35 and 37 areslightly offset from one another so that when the inner sash is swungclosed there is a slight cam or binding action between the two curvedsurfaces which insures a tight joint.

Vhen the inner` sash is closed it may be held closed by any suitablefastening means, such as the locking lug 40 (Figs. 3 and 4) secured onthe inner e-n'd of a stud shaft 42 which is mounted to turn in anaperture in the forward wall of the right hand sash member, the forwardend of the stud shaft 42 being provided with an operating handle 44.Upon swinging this handle 44 downwardly, the lug 40 engages within aslot 46 in the adjacent inner wall of the outer sash. member, the wallof the inner sash member being provided with a clearance slot for thelug. Said slot 46 is provided with an inclined wall 48 so that when thehandle is swung downwardly the lug 40 by acting on the inclined wall 48tends to bind the inner sash against the outer sash so as to insuretight closing` and locking of the window.

With this construction, to open the inner sash, the handle 44 may beturned to unlock the sash and then 'the sash may be swung inwardly so asto move its right hand edge versed. When the reverse side of the windowhas been cleaned, the window may be swung in the reverse direction andthe pivot carriers 15 return to their initial positions, whereupon thelower sash may be swung closed and locked.

The cords 26 and 3() connecting the two carriers 15 as above describedinsure that the pivot pins shall be maintained in proper verticalalinement so that any danger of binding of the inner sash during itssliding movement is eliminated.

The handle 44 is arranged within the space between the planes of thefront sides of the inner and outer sashes, so that the handle on the topinner sash will not interfere with the usual opening and closing of thewindow.

As will be evident to those skilled in the art, our invention permitsvarious modiica tions without departing from the spirit thereof or thescope of the appended claims.

What we claim is:

1. A window having, in combination, a Window case, an outer sash mountedto slide vertically in the case, an inner sash, means for mounting theinner sash in the outer sash whereby it may be moved about a verticalaxis and moved transversely of the outer sash comprising pins extendingvertically in axial alinement in pivotal engagement with one verticaledge of the inner sash, supports for the outer ends of said pins mountedto slide in the outer sash, and means interconnecting said supports forcausing them to move in unison whereby to maintain the pivot pins invertical alinement during movement of the inner sash.
